Electronic Stability Control
(ESC)
The Electronic Stability Control
(ESC) system helps to stabilise the
vehicle during cornering manoeu-
vres.
ESC checks where you are steering
and where the vehicle is actually
going. ESC applies braking pressure
to any one of the vehicle’s brakes
and intervenes in the engine man-
agement system to assist the driver
with keeping the vehicle on the
intended path.It is not a substitute for safe driving
practices. Always adjust your speed
and driving to the road conditions.
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately 3 seconds and goes off then
the ESC is turned on.
OLF054448R
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns, abrupt
manoeuvres, and hydroplaning
on wet surfaces can result in
severe accidents.
WARNING

Driving your vehicle
When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
• When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ESC is
active.
• When the ESC activates, the
engine may not respond to the
accelerator in the usual way.
• If the Cruise Control was in use
when the ESC activates, the Cruise
Control automatically disengages.
The Cruise Control can be reen-
gaged when the road conditions
allow.See “Cruise Control System”
later in this chapter.(if equipped)• When moving out of the mud or
driving on a slippery road, the
engine rpm (revolutions per minute)
may not increase even if you press
the accelerator pedal heavily. This
is to maintain the stability and trac-
tion of the vehicle and does not
indicate a problem.
ESC OFF condition
To cancel ESC operation :
• State 1
Press the ESC OFF button briefly
(ESC OFF indicator light and mes-
sage illuminates). In this state, the
engine control function does not
operate. In other words, the traction
control function does not operate
and only the brake control function
operates.

VSM operation
VSM ON condition
The VSM operates when:
• The Electronic Stability Control
(ESC) is on.
• Vehicle speed is above approxi-
mately 15 km/h on a winding road.
• Vehicle speed is above approxi-
mately 20 km/h when the vehicle is
braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
Information
The VSM does not operate when:
• Driving on a banked road such as a
gradient or incline
• Driving rearward.
• ESC OFF indicator light is on.
• EPS (Electric Power Steering)
warning light ( ) is on.

To cancel VSM operation, press the
ESC OFF button. ESC OFF indicator
light ( ) will illuminate.
To turn on VSM, press the ESC OFF
button again. The ESC OFF indicator
light will go out.
Driving with varying tyre or wheel
sizes may cause the ESC system
to malfunction. When replacing
tyres, make sure they are the
same size as your original tyres
for this vehicle.
NOTICE
i
If the ESC indicator light ( ) or
EPS warning light ( ) stays
on, your vehicle may have a
malfunction with the VSM sys-
tem. When the warning light illu-
minates we recommend that the
vehicle be checked by an autho-
rised HYUNDAI dealer as soon
as possible.

Hill-Start Assist Control (HAC)
(if equipped)
The Hill-Start Assist Control (HAC)
prevents the vehicle from rolling rear-
wards when starting a vehicle from a
stop on a hill. The system operates
the brakes automatically for approxi-
mately 2 seconds and releases the
brake when the accelerator pedal is
depressed or after 2 seconds.
Information
• The HAC does not operate when the
shift lever is in P (Park) or N
(Neutral)
• The HAC activates even though the
ESC (Electronic Stability Control) is
off but does not activate when the
ESC has malfunctioned.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind your vehicle
by blinking the stop light when the
vehicle is braked rapidly and severe-
ly.
The system is activated when:
• The vehicle suddenly stops (vehi-
cle speed is over 55km/h and the
vehicle deceleration is greater than
7 m/s
2)
• The ABS is activating
When vehicle speed is under 40
km/h and the ABS deactivates or the
sudden stop situation is over, the
stop light will stop blinking and the
hazard warning flasher will turn on
automatically.
The hazard warning flasher will turn
off when vehicle speed is over
10km/h after the vehicle has
stopped. Also, it will turn off when the
vehicle is driven at low speed for
some time. You can turn it off manu-
ally by pushing the hazard warning
flasher switch.
i
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.

Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flasher is already on.
Good braking practices Wet brakes can be dangerous! The
brakes may get wet if the vehicle is
driven through standing water or if it
is washed. Your vehicle will not stop
as quickly if the brakes are wet. Wet
brakes may cause the vehicle to pull
to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle under control at all times. If
the braking action does not return to
normal, stop as soon as it is safe to
do so and we recommend that you
call an authorised HYUNDAI dealer
for assistance.
DO NOT drive with your foot resting
on the brake pedal. Even light, but
constant pedal pressure can result in
the brakes overheating, brake wear,
and possibly even brake failure.i
Whenever leaving the vehicle or
parking, always come to a com-
plete stop and continue to
depress the brake pedal. Move
the shift lever into the P (Park)
position, then apply the parking
brake, and place the Engine
Start/Stop button in the OFF
position.
Vehicles with the parking brake
not fully engaged are at risk of
moving inadvertently and caus-
ing injury to yourself or others.
WARNING

5-44
Driving your vehicle
If a tyre goes flat whilst you are driv-
ing, apply the brakes gently and
keep the vehicle pointed straight
ahead whilst you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe location.
Keep your foot firmly on the brake
pedal when the vehicle is stopped to
prevent the vehicle from rolling for-
ward.

Information
• During normal cruise control opera-
tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
• To activate cruise control, depress
the brake pedal at least once after
turning the ignition switch to the
ON position or starting the engine.
This is to check if the brake switch
which is important to cancel cruise
control is in normal condition.
To set Cruise Control speed
1. Push the CRUISE button on the
steering wheel to turn the system
on. The CRUISE indicator will illu-
minate.
2. Accelerate to the desired speed,
which must be more than 40 km/h.3. Push the lever (1) down (SET-) ,
and release it. The SET indicator
light will illuminate.
4. Release the accelerator pedal.
Information
The vehicle may slow down or speed
up slightly whilst going uphill or
downhill.

Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
• Slow down and allow extra follow-
ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
• Turn OFF your Cruise Control. (if
equipped)
• Replace your windscreen wiper
blades when they show signs of
streaking or missing areas on the
windscreen.
• Ensure your tyres have enough
tread. If your tyres do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See “Tyre Tread” in chapter 7.
• Turn on your headlamps to make it
easier for others to see you.
• Driving too fast through large pud-
dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.• If you believe your brakes may be
wet, apply them lightly whilst driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tyre tread
decreases, refer to “Tyre Tread” in
chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times whilst the vehicle is mov-
ing slowly.

Snow or icy conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur.
To drive your vehicle in deep snow, it
may be necessary to use snow tyres
or to install tyre chains on your tyres.
Always carry emergency equipment.
Some of the items you may want to
carry include tyre chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tyresIf you mount snow tyres on your vehi-
cle, make sure to use radial tyres of
the same size and load range as the
original tyres. Mount snow tyres on
all four wheels to balance your vehi-
cle’s handling in all weather condi-
tions. The traction provided by snow
tyres on dry roads may not be as
high as your vehicle's original equip-
ment tyres. Check with the tyre deal-
er for maximum speed recommenda-
tions.
Information
Do not install studded tyres without
first checking local and municipal reg-
ulations for possible restrictions
against their use.
i
WINTER DRIVING
Snow tyres should be equiva-
lent in size and type to the vehi-
cle's standard tyres. Otherwise,
the safety and handling of your
vehicle may be adversely affect-
ed.

Don't let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap-
pen when there is an accumulation
of snow or ice around or near the
rear brakes or if the brakes are wet.
If there is a risk the parking brake
may freeze, apply it only temporarily
whilst you put the shift lever in P
(automatic transaxle) or in first or
reverse gear (manual transaxle) and
block the rear wheels so the vehicle
cannot roll. Then release the parking
brake.Don't let ice and snow accumulate
underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
vehicle to be sure the movement of
the front wheels and the steering
components is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tyre chains, tow straps or
chains, flashlight, emergency flares,
sand, shovel, jumper cables, window
scraper, gloves, ground cloth, cover-
alls, blanket, etc.Don't place foreign objects or
materials in the engine compart-
ment
Placement of foreign object or mate-
rials which prevent cooling of the
engine, in the engine compartment,
may cause a failure or combustion.
The manufacturer is not responsible
for the damage caused by such
placement.
